It'll be easier for us to name the best mid-range Ultrabook once we've tested a few more, but for now we can confidently say the Series 5 UltraTouch offers a comfortable typing experience, attractive design and battery life that isn't great, per se, but at least falls toward the upper range of what we've been seeing from other touchscreen systems.

I've looked at Windows 8 laptops that cost $1,300 or more, as well as ones that dip down below $600. The former tend to be very nice, but hard for everyday consumers to swallow, while the latter can be functional, but plasticky. For $849, the 13-inch Core i5 Series 5 makes a compelling argument, especially when you consider its 6-hour-plus battery life.
